Abstract

OBJECTIVES:

To identify success rates for radial artery cannulation in a pediatric critical care unit using either palpation or ultrasound guidance to cannulate the radial artery.

METHODS:

A prospective randomized comparative study of critically ill children who required invasive monitoring in a tertiary referral center was conducted. All patients were randomized by a stratified block of 4 to either ultrasound-guided or traditional palpation radial artery cannulation. The primary outcomes were the first attempt and total success rates.

RESULTS:

Eighty-four children were enrolled, with 43 randomized to the palpation technique and 41 to the ultrasound-guided technique. Demographic data between the groups were not significantly different. The total success and first attempt rates for the ultrasound-guided group were significantly higher than those for the palpation group (success ratio, 2.03; 95% confidence interval, 1.13-3.64; P = .018; and success ratio, 4.18; 95% confidence interval, 1.57-11.14; P = .004, respectively). The median time to success for the ultrasound-guided group was significantly shorter than that for the palpation group (3.3 versus 10.4 minutes; P < .001). Cannulation complications were lower in the ultrasound-guided group than the palpation group (12.5% versus 53.3%; P < .001).

CONCLUSIONS:

The ultrasound-guided technique could improve the success rate and allow for faster cannulation of radial artery catheterization in critically ill children.
